Rotatable Partition Board for Flexible Lunch Box Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lunch boxes with fixed partitions face issues such as food residue accumulation, difficulty in cleaning, and the need for food processing to fit compartments, which affects food hygiene and appearance.
Innovation Solution
A storage box with rotatably changing compartments, featuring a hinge portion and rotating partition board that adjusts internal space, allowing easy operation and convenient use by firmly positioning the partition board through insertion slots and ribs, preventing deviation and providing bending resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed partition design is adopted, then compartment structure is stable, but food residue accumulates in corner areas and cleaning becomes difficult
Solution Approach 1:
The partition board is changed from a fixed structure to a rotatable structure that can rotate around a hinge portion. This dynamic design allows the partition board to be adjusted to different positions, enabling users to access and clean corner areas that would otherwise be inaccessible with fixed partitions.
Solution Approach 2:
The partition board is divided into separate components: a board member and a rotating portion connected via a hinge portion. This segmentation allows the partition to rotate independently, facilitating cleaning access while maintaining structural integrity during use.
2Device complexity
If fixed partition boards are used, then compartment layout is determined, but food processing (bending or cutting) is required to fit compartments
Solution Approach 1:
The rotatable partition board enables dynamic adjustment of compartment sizes and shapes. Users can rotate the partition to create different compartment configurations, allowing food items of various shapes and sizes to be placed without pre-processing or fitting.
3Adaptability or versatility
If partition board rotation is enabled, then compartment arrangement becomes flexible, but positioning stability may be compromised
Solution Approach 1:
A hinge portion serves as an intermediary mechanism between the board member and the box body. This hinge allows controlled rotation while providing stable positioning at different angles, maintaining both flexibility and stability.
Solution Approach 2:
The partition board system is designed to be user-adjustable through simple rotation around the hinge. The structure itself provides the mechanism for adjustment without requiring additional tools or complex operations, enabling users to easily change compartment arrangements while maintaining stable positioning.

AI summary
A storage box with rotatably changing compartments includes a box body, a partition board and a box cover. The box body includes a base plate and a vertical plate bent and extended from the base plate. A storage space is enclosed by the vertical plate and the base plate. The base plate includes a hinge portion. The partition board includes a board member and a rotating portion arranged on the board member, and the board member is rotatably attached to the hinge portion correspondingly, and the storage space is divided into a first compartment and a second compartment via the board member. The box cover correspondingly covers the box body. Accordingly, the internal space of the box body may be adjusted depending upon the actual needs to achieve easy operation and convenient use thereof.
